Description

사용자 인터페이스로 움직임을 이용하는 장치 및 그 장치로의 입력 제공 방법{A USER INTERFACE USING ACCELERATION FOR INPUT}A device using movement as a user interface and a method for providing input to the device {A USER INTERFACE USING ACCELERATION FOR INPUT}

본 발명은 일반적으로 전자 장치에 관한 것이고, 보다 구체적으로 휴대용 장치로의 입력을 위해 가속을 사용하는 것에 관한 것이다.The present invention relates generally to electronic devices and, more particularly, to the use of acceleration for input into a portable device.

셀룰러 폰, 디지털 카메라, 게임 장치 및 개인용 정보 단말기(Personal Digital Assistant, PDA)와 같은 휴대용 장치는 그 기능을 제어하기 위해 어떤 형태의 사용자 입력 장치를 필요로 한다. 이는, 특히 이들 장치가 더 정교한 기능 및 더 많은 기능성의 그래픽 디스플레이를 가지는 경우에 그러하다.Portable devices such as cellular phones, digital cameras, gaming devices and personal digital assistants (PDAs) require some form of user input device to control their functionality. This is especially the case when these devices have more sophisticated and more functional graphical displays.

터치 스크린은 PDA를 위한 표준 사용자 인터페이스가 되어 왔다. 이들이 정확한(true) 포인팅 장치이기 때문에 이들은 매우 강력하며 직관적(intuitive)이다. 다른 한편으로, 터치 스크린은 연약한(fragile) 플라스틱 필름을 사용한다. 이는 특히 스타일러스 팁에 의해 쉽게 긁히거나, 패이거나(gouged), 찢겨진다.Touch screens have become a standard user interface for PDAs. Because they are true pointing devices, they are very powerful and intuitive. On the other hand, the touch screen uses a fragile plastic film. It is particularly easily scratched, gouged or torn by the stylus tip.

셀룰러 폰, 디지털 카메라 및 게임기는 현재 입력을 위해 다수의 버튼을 사용한다. 예를 들면, "화살표 키"는 메뉴를 통해 좌, 우, 위 및 아래로 이동시켜 디스플레이 상의 콘텐츠를 스크롤하기 위해 사용된다. 선택을 확인 또는 취소하기 위해 또 다른 버튼들이 필요하다. 많은 경우, 복잡한 그래픽 사용자 인터페이스를 조종하기 위해 버튼을 사용하는 것은 쓰기 불편하고 자연스럽지 않다. 또한, 휴대용 장치가 더 소형화되고, 고기능화됨에 따라, 필요한 상당수의 버튼을 위한 공간을 마련하기 어렵다.Cellular phones, digital cameras and game machines currently use a number of buttons for input. For example, an "arrow key" is used to scroll left and right, up and down through menus to scroll content on the display. Further buttons are needed to confirm or cancel the selection. In many cases, using buttons to navigate a complex graphical user interface is inconvenient to use and unnatural. In addition, as portable devices become smaller and more functional, it is difficult to provide space for the required number of buttons.

종래 기술의 네비게이션 버튼을 대신하는 다른 더 소형의 더 직관적인 방법에 대한 필요성이 존재한다.There is a need for other smaller, more intuitive methods that replace the navigation buttons of the prior art.

바람직한 실시예에서, 장치 사용자 인터페이스를 위한 입력 장치로서 가속도계(accelerometers)가 사용된다. 제 1 가속도계는 제 2 가속도계의 방향과 실질적으로 상이한 방향으로 배치된다. 사용자는 장치를 틸트(tilt)나 탭(tap)하거나 또는 틸트하고 탭하여 여러 장치 동작을 호출할 수 있다.In a preferred embodiment, accelerometers are used as input devices for the device user interface. The first accelerometer is disposed in a direction substantially different from the direction of the second accelerometer. The user can tilt or tap the device, or tilt and tap to invoke various device actions.

본 발명의 다른 측면 및 이점은 예로서 본 발명의 원리를 도시하는 첨부 도면과 연결하여 다음의 상세한 설명으로부터 명백해질 것이다.Other aspects and advantages of the invention will be apparent from the following detailed description taken in connection with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

본 발명은 장치의 움직임을 검출하기 위해 하나 이상의 가속 센서를 사용한다. 센서의 가속은 기준으로서 질량을 사용하거나, 장치를 틸트하거나 장치를 탭함으로써 이루어질 수 있다. 하나의 가속도계가 다른 가속도계의 방향과 실질적으로 상이한 방향으로 배치되는 두 개의 가속도계를 사용함으로써 측면에서 측면(side-to-side)(roll) 및 앞에서 뒤(front-to-back)(pitch) 틸트를 측정하기 위한 가속이 감지된다. 이들 움직임은 두 방향으로 사용자 인터페이스를 항해(navigate)하기 위해 화살표 키를 누르는 것의 대안적인 방법으로서 사용된다. 예를 들면, 한 쪽으로 카메라를 틸트하는 것은 그 방향으로 정보를 스크롤할 수 있다. 앞쪽 또는 뒤쪽으로 틸트하는 것은 메뉴를 표시하여 위·아래로 스크롤하는 것과 같은 다른 기능을 호출할 수 있다.The present invention uses one or more acceleration sensors to detect the movement of the device. Acceleration of the sensor can be accomplished by using mass as a reference, tilting the device or tapping the device. By using two accelerometers where one accelerometer is positioned in a direction that is substantially different from the direction of the other accelerometer, side-to-side (roll) and front-to-back pitch tilts Acceleration to measure is detected. These movements are used as an alternative way of pressing arrow keys to navigate the user interface in two directions. For example, tilting the camera to one side can scroll the information in that direction. Tilt forward or backward can call up other functions such as scrolling up and down by displaying a menu.

틸트의 방향을 측정하는 것은 아날로그 기능이어서 비례적 제어를 위해 사용될 수 있다. 예를 들면, 더 많이(further) 틸트하는 것은 더 많이 또는 더 빨리 정보를 스크롤할 수 있다. 이와 반대로, 화살표 버튼은 반복적으로 눌러져야만 한다. 사용자에게의 결과적인 영향은 한 쪽에서 다른 쪽으로 디스플레이를 "쏘는 것(pouring)"처럼 매우 자연스럽고 직관적이다.Measuring the direction of tilt is an analog function and can be used for proportional control. For example, tilting more can scroll the information more or faster. In contrast, the arrow buttons must be pressed repeatedly. The resulting effect on the user is very natural and intuitive, such as "pouring" the display from one side to the other.

본 발명의 또 다른 실시예는 사용자가 장치를 탭했을 때를 탐지하기 위해 가속도계를 사용한다. 탭은 그 전이 성질에 의해 틸트와 구별된다. 틸트는 저주파수 및 DC 신호를 생성하고, 탭은 더 높은 주파수 신호를 생성한다. 하나의 가속도계가 다른 가속도계와 실질적으로 상이한 방향인 두 개의 가속도계를 다시 사용함으로써 탭의 방향이 식별될 수 있다. 장치의 왼쪽 위(the top left of the appliance)를 탭하는 것은 롤 센서의 한 방향으로 신호를 제공하고, 오른쪽 위(the top right of the appliance)를 탭하는 것은 반대 방향으로 신호를 제공한다. 이와 유사하게, 장치의 위쪽 뒤와 아래쪽 뒤(the top back and bottom back of the appliance)를 탭하는 것은 양 및 음의 피치 신호(positive and negative pitch signals)를 제공한다.Another embodiment of the invention uses an accelerometer to detect when the user taps the device. Taps are distinguished from tilt by their transition properties. Tilt produces low frequency and DC signals, and taps produce higher frequency signals. The direction of the tap can be identified by reusing two accelerometers in which one accelerometer is substantially different from the other accelerometer. Tapping the top left of the appliance provides a signal in one direction of the roll sensor, and tapping the top right of the appliance provides a signal in the opposite direction. Similarly, tapping the top back and bottom back of the appliance provides positive and negative pitch signals.

틸트 및 탭의 두 동작은 통합된 사용자 인터페이스에서 함께 사용될 수 있다. 예를 들면, 위에서 설명한 바와 같이, 디지털 카메라에서, 카메라를 틸트하는 것은 다수의 저장된 영상 또는 메뉴 항목을 스크롤한다. 그 후, 카메라 케이스를 탭하는 것은 선택 또는 확인을 나타낸다. 이는 4개의 화살표 버튼 및 "OK" 버튼을 가진 종래의 카메라 사용자 인터페이스의 기능을 대신한다.The two actions, tilt and tap, can be used together in an integrated user interface. For example, as described above, in a digital camera, tilting the camera scrolls through a number of stored images or menu items. Then tapping the camera case indicates selection or confirmation. This replaces the functionality of a conventional camera user interface with four arrow buttons and an "OK" button.

도 1은 디지털 카메라(100) 상의 화살표 기능부(106, 108, 110, 112) 및 "OK" 기능부(104)를 도시하는 도면이다. 화살표 기능부(106, 108, 110, 112)는 카메라 스크린(120)의 위와 아래 그리고 양옆에 배치된다. OK 기능부(104)는카메라(100)의 오른쪽 위에 배치된다.FIG. 1 is a diagram showing arrow functions 106, 108, 110, 112 and "OK" function 104 on digital camera 100. The arrow functions 106, 108, 110, 112 are disposed above, below, and on both sides of the camera screen 120. The OK function 104 is disposed above the right side of the camera 100.

도 2는 카메라 스크린(202) 아래에 가속도계 모듈(204)을 포함하는 디지털 카메라(200)의 도면이다. 가속도계 모듈(204)은 서로 직교하는 두 개의 가속도계를 포함한다. 도 2에 도시되어 있는 카메라를 우측 또는 좌측으로 틸트하는 것은 도 1에서의 화살표 기능부(106, 110)를 대신한다. 도 2에 도시되는 카메라를 탭하는 것은 도 1에 도시된 OK 버튼(104)을 대신한다.2 is a diagram of a digital camera 200 including an accelerometer module 204 under the camera screen 202. Accelerometer module 204 includes two accelerometers orthogonal to each other. Tilt the camera shown in FIG. 2 to the right or left replaces the arrow functions 106 and 110 in FIG. 1. Tapping the camera shown in FIG. 2 replaces the OK button 104 shown in FIG.

이 애플리케이션에 적합한 가속 센서가 이용 가능하다. 예를 들면, 내셔널 세미컨덕터사(National Semiconductor)는 두 개의 직교 마이크로 기계형 실리콘 가속기(orthogonal micomachined silicon accelerometers)를 단일의 패키지로 제조했다. 이 부분은 소형이고 비고가이고 저전력형이며, 공통의 마이크로프로세서와 용이하게 인터페이스한다.Acceleration sensors suitable for this application are available. For example, National Semiconductor manufactured two orthogonal micomachined silicon accelerometers in a single package. This part is small, expensive, low power, and easily interfaces with common microprocessors.
